Description: The Device Identification and Driver Management (DIDM) project addresses the need to provide device-specific functionality. Device-specific functionality is code that performs a feature, and the code is knowledgeable of the capability and limitations of the device. For example, configuring VLANs and adjusting FlowMods are features, and there may be different implementations for different device types. Device-specific functionality is implemented as Device Drivers.

Description: LISP (RFC6830) is a protocol that enables separation of Endpoint Identity (EID) from Routing Location (RLOC) by defining an overlay in the EID space which is mapped to the underlying network in the RLOC space. LISP also provides a Mapping Service that provides the EID-to-RLOC mapping information including forwarding policy (load balancing, traffic engineering, etc.) to LISP routers for tunneling and forwarding purposes. The LISP Mapping Service can serve the mapping data to dataplane nodes as well as to ODL applications. To leverage this service, a northbound API allows OpenDaylight applications and services to define the mappings and policies in the LISP Mapping Service. This project also includes a southbound LISP plugin that enables LISP dataplane devices to interact with the OpenDaylight via the LISP protocol.

Key Updates for Lithium: Improved ELP Processing, NB API transitioned to MD-SAL, Continuous integration with Service Function Chaining, Neutron enhancements

Specifically the project has developed a plugin aiming to support OpenFlow 1.0 and 1.3.x. It can be extended to add support for subsequent OpenFlow specifications. The plugin is based on the Model Driven Service Abstraction Layer (MD-SAL) architecture

Key Updates for Lithium: For Lithium the OpenFlow Plugin underwent a complete rearchitecture, this new OpenFlow 1.0/1.3 MD-SAL based plugin is distinct from the old OpenFlow 1.0 plugin which was based on the API driven SAL (AD-SAL) architecture; support for Table Type Patterns added

Description: Provides application persistence logic for query-able and non-modeled data (aka, object store), which is needed for many SDN applications like the AAA, AADS and TSDR projects. This framework unifies the common tasks of persisting data so that applications can follow a systematic method to implement their persistence logic with well-defined abstractions and separation of concerns between business and persistence logic.

Description: Reservation is meant to provide dynamic low level resource reservation so that users can get network as a service, connectivity or a pool of resources (ports, bandwidth) for a specific period of time. The idea behind the reservation application is to be able to have end to end multi-layer provisioning. Assume the two end to be two ports in a device. The link provisioning could be done based on information such as latency, bandwidth, etc. Link reservation also may consider the period of time (duration), and taking into account the cost of reservation.

Description: SNBI uses a zero-touch approach to bootstrapping that leverages manufacturer-installed IEEE 802.1AR certificates to secure even the initial communications. SNBI devices and controllers automatically discover each other, get an IP-address assigned, and establish secure IP connectivity. In addition, this discovery process reveals the physical topology of the network, exposes each type of a device, and assigns the domain for each device. This device type and domain information can also be used for initiating controller federation processes. As part of the SNBI project a basic infrastructure to host, run, and lifecycle-manage multiple network components/functions within a network device is created. These components/functions can include individual network element services, such as performance measurement, traffic-sniffing functionality, or traffic transformation functionality.

Key Updates for Lithium: Added Linux side abstraction layer for forwading elements along with enhancements to feature abstraction and bootstrapping infrastructure

Description: OpenDaylight Service Function Chaining (SFC) provides the ability to define an ordered list of a network services (e.g. firewalls, load balancers). These service are then "stitched" together in the network to create a service chain. This project provides the infrastructure (chaining logic, APIs) needed for ODL to provision a service chain in the network and an end-user application for defining such chains.

Key Updates for Lithium: Added Yang models for expressing service function chains; SFC receiver for intent expressions from REST & RPC; UI for service chain construction; LISP support; function grouping for load balancing; Openflow renderer for NSH, MPLS & VLAN; Southbound REST interface; SFC-OVS for SFF bridges, tunnels, and ports CRUD via OVSDB; Classifier (IP Tables based) for classifying packets into selected Service Chains; Integration with ODL GBP project

Description: The SNMP Project address the need for a southbound plugin that allows applications and controller services to interact with devices using SNMP. The SNMP southbound plugin will allow applications acting as an SNMP Manager to interact with devices that support an SNMP agent. This project seeks to implement a general SNMP implementation, which differs from the SNMP4SDN as that project leverages select SNMP features to implement specific use cases.

Description: SXP is an IETF published control protocol designed to propagate the binding between an IP address and a Source Group Tag (SGT). Within SXP, source groups are endpoints connecting to the network which have common network policies. Each source group is identified by a unique SGT value. SGTs can be used by firewalls (FW) to create topology independent Access Control List (ACL) decisions - since source and destination IP/SGT information can be sent to the firewall. This also provides FW ACL automation since at the time of new endpoint attachment to the network, SXP can update the FW of the new IP/SGT for the endpoint. By extending this type of topology independent policy definition and automation through the SDN controller, it becomes possible to apply it to other services and networking devices. Within ODL, manipulation of policy groups will often use Group Based Policy (GBP) infrastructure. Source groups in SXP have the same meaning as endpoint groups in ODL GBP. Thus the GBP infrastructure in ODL can be used with SXP SGTs.

OpenDaylight Virtual Tenant Network (VTN) is an application that provides multi-tenant virtual network on an SDN controller. VTN allows the users to define the network with a look and feel of conventional L2/L3 network. Once the network is designed on VTN, it will automatically be mapped into underlying physical network, and then configured on the individual switch leveraging SDN control protocol. The definition of logical plane makes it possible not only to hide the complexity of the underlying network but also to better manage network resources. It achieves reducing reconfiguration time of network services and minimizing network configuration errors.

Key Updates for Lithium: Migration to MD-SAL; Significant improvements to policy management in VTN Manager; Support for Microsoft SVCMM

The USC framework provides a central server to coordinate encrypted communications between endpoints. USC provides a client-side agent that can inform the controller about its encryption capabilities and can be instructed to encrypt select flows based on business policies. One possible use case of this is to encrypt controller-to-controller communications. However the framework is very flexible and client side software is available for multiple platforms and device types. This enables USC & ODL to centralize the coordination of encryption across a wide array of endpoint and device types.
